BACKGROUND 1. Technical Field

Present invention embodiments relate to monitoring performance of network software applications, and more specifically, to modifying compiled applications to intercept data relating to computing performance of serving requests.

2. Discussion of the Related Art

A network software application refers to an application that utilizes a network such as the Internet to perform useful functions, such as responding to requests from clients applications. One example of a network software application is a web application, which is a client-server computer program in which a web browser or other client application provides requests to a server-side application in order to process and receive data, etc. In order to track the performance of a network software application, statistics such as latency, data upload and download rates, and error rates may be requested. However, some applications may not inherently include functions for obtaining such statistics, making tracking of performance difficult.

SUMMARY

According to one embodiment of the present invention, a computer system modifies a compiled application to monitor performance. A request routing function of the compiled application is replaced with jump code that directs processing to a data collection function and backing up the request routing function. In response to receiving, during execution of the compiled application, an incoming request from a remote device for handling by the request routing function, the data collection function is executed based on the jump code. Using the data collection function, data associated with the incoming request is collected, the data comprising performance metrics. The backup of the request routing function is called using the data collection function to process the request and provide a response. Embodiments of the present invention further include a method and program product for modifying a compiled application to monitor performance in substantially the same manner described above.

DETAILED DESCRIPTION

Present invention embodiments relate to monitoring performance of network software applications, and more specifically, to modifying compiled applications to intercept data relating to computing performance of serving requests. A network software application, such as a web application, may be hosted on a server and may respond to requests received from client applications, such as HyperText Transfer Protocol (HTTP) requests and the like. In order to track or monitor the performance of an application, statistics relating to the application's performance may be collected, including latency, upload and download rates, and error rates. Typically, products that monitor the performance of applications will obtain performance metrics by intercepting some function call that is called whenever a request is received from a client. For example, Java™ and Python® provide hooks that can be used to obtain performance metrics in this manner.

However, in some programming languages, such as Go, when an application is compiled into a binary file, there may not be a mechanism for intercepting function calls. Existing solutions require a binary file to be dynamically linked, which is less efficient and less portable than static linking, since dynamic linking requires the presence of a library on the local system hosting the application. Moreover, existing solutions may require inclusion of a symbol table, which can introduce vulnerabilities to applications.

Present invention embodiments monitor performance by modifying the machine code of compiled applications to enable monitoring of requests and responses without requiring manual code instrumentation. In particular, a request routing function that is responsible for handling incoming requests is identified in a compiled application and replaced with a branch or jump command or code that can be configured to call or jump to any arbitrary function. The request routing function is backed up elsewhere in memory, and a data collection function is inserted into the application library. When the application receives a request, the request is initially handled by the jump code instead of the request routing function; the jump code calls the data collection function to initiate collection of data, and the data collection function then calls the backup copy of the request routing function so that the application can respond to the request. Thus, present invention embodiments enable collection of data, including performance metrics, from a compiled application by modifying the application in a manner that does not impact the functionality of the application.

In particular, client module 115 may transmit a request to a network application, which can process the request (e.g., by generating data, fetching data, etc.) and send a response back to client module 115. In some embodiments, client module 115 is a web client, such as a web browser or other application, and the requests and responses can include HyperText Transfer Protocol (HTTP) and/or HyperText Transfer Protocol Secure (HTTPS) requests and responses. For example, client module 115 may send a request to application 135 to request a particular web page to be transmitted to client module 115. Additionally or alternatively, a user of client device 105 may input data to client module 115 that can be included in a request sent to application 135 for processing. Client module 115 may include a user interface, such as a graphical user interface, for presenting data to a user of client device 105 and/or obtaining input from a user of client device 105.

Network interface 121 enables components of application server 120 to send and receive data over a network, such as network 155. In general, application server 120 hosts one or more applications (e.g., application 135) that can respond to requests received from client applications (e.g., client module 115) via a network (e.g., network 155). Moreover, application server 120 may intercept data from hosted applications in order to obtain performance metrics. Application server 120 may include internal and external hardware components, as depicted and described in further detail with respect to FIG. 4.

Compiler

130, code module 132, application 135, and/or data management module 137 may include one or more modules or units to perform various functions of present invention embodiments described below. Compiler 130, code module 132, application 135, and/or data management module 137 may be implemented by any combination of any quantity of software and/or hardware modules or units, and may reside within memory 125 of application server 120 for execution by a processor, such as processor 122.

Compiler

130 may include any known or other computer program for translating code from one programming language into another. In particular, compiler 130 may translate source code of a high-level programming language into a lower-level programming language (e.g., assembly language, object code, and/or machine code) to create an executable program. In some embodiments, compiler 130 compiles source code in the Go programming language into an executable program. Compiler 130 may import packages from one or more sources, such as storage 140 of application server 120 and/or storage 150 of library server 145, for including additional code in an application during compilation.

Code module

132 is a module that automatically modifies applications in order to monitor performance. Code module 132 may modify machine code of application 135 in accordance with present invention embodiments in order to, e.g., insert jump code, back up a request routing function, insert a data collection function, and the like. Code module 132 may automatically modify application 135 prior to execution, such as at start-up or initialization.

Application

135 is a server-side application that receives requests from client applications (e.g., client module 115), processes requests, and responds to the requests. Application 135 may include any compiled application, and may be compiled by compiler 130 or another compiler; in some embodiments, application 135 is a compiled Go application. Application 135 may be modified as a result of importing a package such that data may be intercepted from application 135 during runtime. In particular, application 135 may contain code that causes application 135 to be modified during initialization such that performance metrics can be obtained from application 135 during runtime. Application 135 is depicted and described in further detail below with respect to FIG. 2.

Data management module

137 may obtain, manage, and/or share data intercepted from application 135, including data relating to the performance of application 135. In particular, data management module 137 may manage data pertaining to latency, upload and download speeds, error rates, and any other network statistics indicative of the performance of application 135. Data management module 137 may transmit data collected about the performance of applications to one or more external entities via network 155 and/or may store the data in persistent storage (e.g., in storage 140). Thus, data intercepted from applications may be stored and/or shared for purposes such as diagnosing network issues, troubleshooting applications, and the like.

Storage

140 may include any non-volatile storage media known in the art. For example, storage 140 can be implemented with a tape library, optical library, one or more independent hard disk drives, or multiple hard disk drives in a redundant array of independent disks (RAID). Similarly, data in storage 140 may conform to any suitable storage architecture known in the art, such as a file, a relational database, an object-oriented database, and/or one or more tables. In some embodiments, storage 140 may store data relating to the performance of applications executing on application server 120, including data pertaining to latency, upload and download speeds, error rates, and other network statistics. Performance metrics stored in storage 140 may be stored as time-series data. Additionally or alternatively, storage 140 may include any packages imported from external sources, such as storage 150 of library server 145.

Library server 145 may each include a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of executing computer readable program instructions. Network interface 146 enables components of library server 145 to send and receive data over a network, such as network 155. In general, library server 145 hosts packages that can be imported into applications during compilation. Library server 145 may include internal and external hardware components, as depicted and described in further detail with respect to FIG. 4.

Storage

150 may include any non-volatile storage media known in the art. For example, storage 150 can be implemented with a tape library, optical library, one or more independent hard disk drives, or multiple hard disk drives in a redundant array of independent disks (RAID). Similarly, data in storage 150 may conform to any suitable storage architecture known in the art, such as a file, a relational database, an object-oriented database, and/or one or more tables. Storage 150 may store any data, including packages that can be imported into applications during compilation. In particular, storage 150 may include a package that contains instructions for generating a jump command or code in an application compiled by a compiler, as well as instructions for inserting the jump command or code in a place of a request routing function of an application, generating a backup of the request routing function, and inserting a data collection function.

Network

155 may include a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and includes wired, wireless, or fiber optic connections. In general, network 155 can be any combination of connections and protocols known in the art that will support communications between client device 105, application server 120, and/or library server 145 via their respective network interfaces in accordance with embodiments of the present invention.

FIG. 2 is a block diagram depicting an application 135 that is modified in order to monitor performance in accordance with an embodiment of the present invention. As depicted, application 135 includes a jump code 210, a data collection function 220, a backup request routing function 230, and a request handler 240.

In one embodiment, a request 205 is received by application 135 and is initially handled by jump code 210, which calls or jumps to data collection function 220 at operation 215. Data collection function 220 collects data relating to the request and calls backup request routing function 230 at call 225 so that request 205 can be served. Backup request routing function 230 identifies and calls the appropriate handler, request handler 240, which is called at call 235. It should be appreciated that application 135 may include multiple handlers for various requests (e.g., a handler for HTTP and/or HTTPS requests, a handler for File Transfer Protocol (FTP) requests, a handler for requests for certain data types, etc.), and that request handler 240 is selected by backup request routing function 230 as the appropriate handler for request 205. Request handler 240 provides data that is requested by request 205 to backup request routing function 230 via call 245, and additional data relating to the processing of request 205 is shared to data collection function at call 250. Application 135 transmits response 255, which is a response to request 205 (e.g., containing data generated and/or obtained by request handler 240), to the client that transmitted requested 205 (e.g., client module 115 of client device 105).

Application

135 is modified at compilation by importing a package that causes compiler 130 to convert the original request routing function from a private function to a public function. Whereas a private function can only be called by a parent function, a public function can be called by other functions, so converting the original request routing function to a public function enables the original request routing function to be located and backed up to another location in memory when compiled application 135 is executing. The original request routing function may be responsible for routing incoming requests (e.g., request 205) to a handler function (e.g., request handler 240). Jump code 210 and data collection function 220 may also be included in the imported package for insertion into application 135 during compilation.

In some embodiments, the request routing function is converted to a public function by a compile directive. For example, in the Go programming language, the directive “//go:linkname ServeHTTP net/http.serverHandler.ServeHTTP” instructs the compiler to use “net/http.serverHandler.ServeHTTP” as the object file symbol name for the variable or function declared as “ServeHTTP” in the source code.

When compiled application 135 is initialized, the machine code of the request routing function, now a public function, is copied to another location in memory to create backup request routing function 230, and the original request routing function is replaced by jump code 210. In particular, the request routing function's machine code may be copied to a large predefined function in memory. In some embodiments, backup request routing function 230 is inserted into a memory space within data collection function 220 that was previously reserved by a space hold function. In some embodiments, the addresses of RIP register-related operation instructions may be modified due to the instruction-relative addressing modes of 64-bit architecture.

While initializing compiled application 135, the memory of the public request routing function is made writeable and executable. A programming language-specific command may be executed to change access protections for the memory of the public request routing function. For example, in the Go programming language, “syscall.Mprotect” is called to change protections for the memory of the public request routing function. Next, the request routing function, now public, writeable, and executable, is replaced by jump code 210, and the memory of jump code 210 is made readable and executable. Request handler 240 is loaded into memory along with other functions (such as other handlers, etc.) of application 135 to complete initialization of application 135.

Thus, during execution of application 135, request 205 is initially intercepted by jump code 210, since jump code 210 occupies the memory space previously occupied by the original request routing function. Jump code 210 jumps to data collection function 220 at operation 215, which intercepts data relating to request 205 (e.g., performance metrics) before request 205 is passed to backup request routing function 230 and request handler 240. Data collection function 220 may also intercept, at call 250, data relating to request 205 after request 205 is processed by request handler 240 (i.e. data relating to response 255). Data collection function 220 may share data relating to request 205 and/or response 255 with one or more destinations (e.g., data management module 137), depicted at 260.

FIG. 3 is a flow chart depicting a method 300 of monitoring performance of a compiled application in accordance with an embodiment of the present invention.

Jump code is generated at operation 310. An assembly code file is created for the architecture of the target system's processor (e.g., processor 122 of application server 120). The jump code includes code (e.g., program instructions, etc.) that calls or jumps to an arbitrary function for collecting data. The jump code may be included in the library, while data collection functions and instructions to modify an application may be included in a package.

In some embodiments in which application 135 is compiled in the Go programming language, the jump code is generated by first building assembly code with a command such as “CGO_Enabled=0, GOOS=Linux GOARCH=amd64 go build” which indicates that the target architecture's operating system is Linux-based and that the processor architecture is a 64-bit processor manufactured by AMD. Next, disassembled machine code is obtained with the command “obj dump-s machine_code>machine_code.s,” which outputs a disassembled machine code file. The function “GetMachineCode” is located within the machine_code.s file and the machine code of that function is obtained and added to jump code of the target system's architecture, modifying the jump code's address to include the data collection function address.

The package is imported for compilation at operation 320. Compiler 130 may import the package from an external source, such as storage 150 of library server 145. The package may be imported prior to, or during, compilation of an application, such as application 135.

The request routing function is made public at operation 330. When compiler 130 is compiling source code to generate application 135, the original request routing function is identified and converted from a private function to a public function. By converting the request routing function to a public function, the request routing function can be called by other functions that are not a parent function of the request routing function.

The application is compiled at operation 340. When compiler 130 compiles application 135, compiler 130 enables access to code from the imported package and library, including code for data collection function 220, jump code 210, and instructions to replace the original, now-public request routing function with jump code 210 and to back up the request routing function.

The application is initialized and the request routing function is backed up and replaced by jump code at operation 350. Code module 132 may back up the request routing function and insert jump code. During pre-execution of application 135, jump code 210 replaces the original request routing function, which is copied elsewhere in memory to create backup request routing function 230. In some embodiments, space is reserved by data collection function 220 for backup request routing function 230.

Data relating to a request is intercepted at operation 360. An incoming request is first received by jump code 210, which calls data collection function 220 in order to collect data relating to the request. Data collection function 220 then calls backup request routing function 230, which enables the request to be processed as intended: backup request routing function 230 routes the request to the appropriate handler (e.g., request handler 240), and a response is received. Information relating to the response is also collected by data collection function 220. Data that is collected prior to processing a request may include request metrics, such as a start time, parameters in the request, and a uniform resource locator (URL) of the request, and data that is collected after processing the request may include metrics such as an end time, status code, and the like.

The intercepted data is shared at operation 370. Intercepted data may be shared to an external application, such as data management module 137, where the intercepted data can be managed for further analysis. Analysis of intercepted data may be conducted to perform diagnostics or troubleshooting of network or computing issues, and/or intercepted data may be stored to observe performance history.

Present invention embodiments advantageously enable the modification of compiled applications in an automatic manner to monitor performance. Compiled applications that may not inherently include functions for obtaining such statistics can be modified in a manner that enables performance metrics to be collected and analyzed. Furthermore, present invention embodiments do not require manual customization of code in order to modify compiled applications, enabling performance metrics to be collected from an application in an fully automated manner (e.g., by importing a package). Thus, a user is not required to manually configure the application, nor have knowledge of the programming language of the compiled application, the jump code, etc.

The programs described herein are identified based upon the application for which they are implemented in a specific embodiment of the invention. However, it should be appreciated that any particular program nomenclature herein is used merely for convenience, and thus the invention should not be limited to use solely in any specific application identified and/or implied by such nomenclature.
